EPCOS part J3356K** is a **varistor** (voltage-dependent resistor) designed for **overvoltage protection** in electronic circuits.

The EPCOS part J3356K is a varistor (voltage-dependent resistor) designed for overvoltage protection in electronic circuits. Below are its key specifications, descriptions, and features:

Specifications:

  • Type: Metal Oxide Varistor (MOV)
  • Maximum Voltage (AC): 300V RMS
  • Maximum Voltage (DC): 385V
  • Clamping Voltage (at 50A): 775V
  • Peak Current (8/20µs): 4500A
  • Energy Absorption (10/1000µs): 115J
  • Operating Temperature Range: -40°C to +85°C
  • Capacitance (at 1kHz, 1V RMS): ~100pF
  • Lead Spacing: 15mm
  • Package Type: Radial Leaded (Disc)

Descriptions:

  • Designed for surge protection in AC/DC power lines, industrial equipment, and consumer electronics.
  • Provides fast response to transient voltage spikes (e.g., lightning, switching surges).
  • ZnO-based construction ensures high energy absorption and durability.

Features:

  • High surge current capability (up to 4500A).
  • Low leakage current in normal operation.
  • RoHS compliant (lead-free).
  • Reliable long-term performance with stable clamping characteristics.

This varistor is commonly used in power supplies, inverters, and surge protectors to safeguard sensitive components from voltage transients.
